I think she must have lipsing at least once. Example, when she had a cold or something like that. But yeah, Ayu mostly never lipsings at all. In concerts, sometimes, she stops singing a start dancing (Trauma) and she communicates a lot with her fans and often scream all kinds of stuff to the audience.

I doubt she's the only one not lipsinging though.

Most Chinese artists lipsing though. Especially Jolin.
